Exhibition: NOW, NEAR, NEXT,The digital exhibition NOW, NEAR, NEXT, documents in an exciting way current projects and working methods of the NAX partners and focuses on the transformation of architecture and construction. The consistent German values such as perfectionism, quality in construction and project management, reliable engineering services and on-time delivery are enhanced by the experimental, the courageous, the different, the creative, the unfinished and perhaps also the typically "un-German". Research and development play just as big a role as new materials and (digital) processes.

SOMNIUM featured in "Stahlbau"As part of the extension of the Johannes Kepler Universität in Linz, we were in charge of the structural engineering of the SOMNIUM, a free-form platform on the highest building on the campus. The viewing terrace, which is spatially framed by a trellis for future vegetation, serves as a remote oasis of relaxation for campus visitors.
Now the project is featured in the April issue of "Stahlbau" by Ernst und Sohn, Berlin. The authors are Thomas Schaumberger and Arne Hofmann from Bollinger+Grohmann Vienna.

Competitionline Ranking 2020The competitionline-Ranking is the only architects' ranking in the German-speaking world that is based exclusively on competition results. Once a year, the competitionline editorial team evaluates all the competition results published on competitionline.com and creates the ranking of the most successful offices from them.
We are very pleased about the good rankings of our office in the following categories:
3rd place in the category STRUCTURAL ENGINEERS
6th place in the category CIVIL ENGINEERS
3rd place in the category BUILDING PHYSICS
2nd place in competition: NICE HQ, Oderzo"Nice Headquarter" is designed as a high-tech building. The key characteristics are the transparency and lightness of the façades and the roof, which is a monolithic element that opens and closes according to the sun position and weather conditions. It provides a dynamic and flexible space for the inner courtyard.
A set of integrated lights enhances the building's perception at night, maintaining a high level of visibility and a sober profile blending with the surrounding environment.
Bollinger+Grohmann was responsible for structural and façade engineering.

Stefan Polónyi (1930–2021)We received the sad news that Stefan Polónyi has passed away on April 9.
Stefan Polónyi was a leading builder, master teacher, inventor, pioneer and role model. His exemplary contribution in science, teaching and practice strengthened the self-image of engineers and consistently enhanced constructive interaction between architects and engineers. We will miss him. Our thoughts are with his family.

"WOOD. Change the present. Build the future."After one year of research on timber structures, Bollinger+Grohmann and Park Associati are working on a publication to collect all the information. How did we get the results of our research on wood? We combined our expertise through the applied exercise of re-engineering.
Fritz-Kissel-Siedlung, Frankfurt: ProcessThe speedy construction process in Frankfurt's Fritz-Kissel-Siedlung is impressive. After the building permit was granted in September 2020, the first tenants moved into the apartments in mid-December.
Since several construction steps happen at the same time, you can follow every timber module addition phase on the construction site.
Bollinger+Grohmann was already in charge of the feasibility study for fire protection and the structural design for the extension in 2017. We are now responsible for the entire fire protection concept and the structural engineering for the existing structures.
